	<p class="tip">
		<em>NOTE!</em>
	</p>
	<ul>
		<li>The extractor type was added in <span class="version">v2.17.6</span> and allows you to apply two parsers to a column:
			<ul>
				<li>In this demo, the last column contains select dropdowns that have "good", "medium" and "bad" options.</li>
				<li>So there is a need to use a parser to extract content from the selected option within the select and then use the grades parser to give each grade a sortable value.</li>
				<li>Thanks to <a href="https://github.com/TheSin-">TheSin-</a> for adding this functionality!</li>
			</ul>
		</li>
		<li>The extractor <em>is always</em> used before the parser.</li>
		<li>Individual columns can be modified by adding the following (they all do the same thing), set in order of priority:
			<ul>
				<li>jQuery data <code>data-extractor="select"</code>.</li>
				<li>metadata <code>class="{ extractor: 'select'}"</code>. This requires the metadata plugin.</li>
				<li>headers option <code>headers : { 0 : { extractor : 'select' } }</code>.</li>
				<li>header class name <code>class="extractor-select"</code>.</li>
			</ul>
		</li>
